ALT key problem

<< < (2/4) > >>

ayryq:
Also, this whole thread (and a couple others) got pushed to rss, one post at a time. Kind of weird.

tomos:
Since the keyboard interface provides only one action for the ALT key, both ALT keys should work to perform the designated action.

right Alt (AltGr) often works the same as Ctrl+Alt (seems to be the other way round: https://en.wikipedia.org/wiki/AltGr_key#Control_.2B_Alt_as_a_substitute although I have some older software where AltGr will work same as a Ctrl+Alt+ shortcut)

Some interesting related queries:

Actually, that's incorrect.  They give different virtual keycodes, for the express means of using them differently. 

The Virtual Key Code for Alt is VK_MENU, but is extended into VK_RMENU, and VK_LMENU.

Try CTRL+ALT+DEL using the keys on the right side of the keyboard.  It doesn't work.  So this is more a function of implementation, than error.  And if the workaround works, it seems that it may be functioning as designed- that's mouser's call, though it will affect at least myself if he does change it.

The distinct Virtual KeyCodes from MSDN:

VK_MENU
0x12
ALT key
VK_LMENU
0xA4
Left MENU key
VK_RMENU
0xA5
Right MENU key

To Tom's excellent point, when you press right alt you get the following:
vkCode: 162, wparam: 260, lparam: 3398032
vkCode: 165, wparam: 260, lparam: 3398032

And when you release, you get the following:
vkCode: 162, wparam: 257, lparam: 3398032
vkCode: 165, wparam: 257, lparam: 3398032

It's sending two keys - the shortcut for CTRL+ALT.

AltGr+Del used to do the same as CTRL+ALT+DEL, but it's handled at a lower level than normal key combinations now.

mikeyww:
I haven't made myself clear.  The following screenshot shows that pressing ALT plus a number key should launch a program.



I would like this FARR feature to work with both ALT keys.

mouser:
You are correct, I will make it so that either alt button works in launching items with that option.
